They are insanely easy to install but can be difficult to remove depending on the person. I quickly figured out how to remove them, but the average Joe might not be so lucky. This could be good if you're worried about someone taking your wheels. This is definitely an easy way to get colored nuts without painting. However, they do not sit completely flush with the clamping nut and cause a "nipple" effect when pushed out slightly. You can't tell until you go down and inspect them. There didn't seem to be any storage issues, but we'll see over time.
